I got the reason why the dude married the bitch!
The dude married the bitch beacause in 3 months of dating (or hooking up, since we all know our dude) she become morbidly obese, so our boy thought she got pregnant and tried to move to another city called Paradise, but the bitch found him and forced him to marry her.
BUT THIS DEPENDS ON THE GAME, IN POSTAL 1 we know the dude (wich probably is the only dude with a name that is not the dude) was a good guy so this is where the history change. In postal 2 lore the dude tried to escape to paradise but was found by her and due to he leaving everything behind to escape, he had to live in a camper. While in Postal he moved to paradise with time, he bought a house and lived with the bitch, until she stopped caring about him, he slowly got psychosis and well, yk
